Abstract
Addition of small amounts of oxidic compounds of aluminum, cadmium, magnesium, manganese, nickel, uranium, and the rare earths to iron-potassium-vanadium oxide catalysts useful in the dehydrogenation of hydrocarbons to the corresponding more unsaturated hydrocarbons results in an improved catalyst.
Claims25
A catalyst for the dehydrogenation of hydrocarbons to more unsaturated hydrocarbons comprising a mixture having:
- (a) from about 35 to about 67 percent by weight of an iron oxide, measured as iron metal;
- (b) from about 4 to about 25 percent by weight of potassium oxide measured as potassium metal;
- (c) from about 0.005 to about 5 percent by weight of a vanadium oxide, measured as vanadium metal;
- (d) from about 0.005 to about 9 percent by weight of an additive oxide selected from the group consisting of an oxide of cadmium, magnesium, manganese, nickel, a member of a rare earth series, uranium, and mixtures thereof measured as the individual metal;
- and
- (e) from 0 to about 21 percent by weight of a chromium oxide measured as chromium metal.
